Asian markets retreat as trade deal euphoria fades

Hong Kong: Asian markets fell Monday after Donald Trump's top economics adviser downplayed the chances of a quick deal to end the China-US trade war, taking the wind out of the sails of last week's rally.

The US leader fuelled a surge in the region's equities Friday by tweeting that he had held positive talks with Chinese President Xi Jinping, before a report said he had even asked officials to draw up a draft bill with an eye on a potential agreement.

But White House adviser Larry Kudlow later tempered expectations, telling CNBC "there's no massive movement to deal with trade".

The news sent US markets into the red, snapping a three-day rally on Wall Street, and sending Asian investors rushing for the door.

"Investors are far too wary of an empty promise," said Stephen Innes, head of Asia-Pacific trade at OANDA.

"But ultimately, they will need to decide how much of President Trump's olive branch to China was a ploy to boost equity markets ahead of the US mid-term elections on Tuesday and how much of it is a bona fide attempt to reach an agreement."

Hong Kong - which climbed more than four percent Friday in its best day for almost seven years - sank more than two percent, while Shanghai ended down 0.4 per cent.

Dealers are keeping tabs on a massive import expo in Shanghai that Xi opened Monday by telling delegates China would increase efforts to open up its economy.

Tokyo finished 1.6 per cent lower, Singapore dropped 1.7 per cent and Seoul was 0.9 per cent off. Wellington and Taipei were also deep in negative territory, while Sydney dropped 0.5 per cent.

However, Manila gained 0.8 per cent.

Traders are now keeping an eye on the US mid-term elections Tuesday, which are seen as a vote on Trump's performance since taking the White House, with the Democrats looking to take control of the House of Representatives.

A win for them could also raise the chances of Trump being impeached, fuelling uncertainty.

"The mid-term elections carry a considerable amount of political and market risk not to mention legal risk for the current administration so that the markets could swivel higher or lower on the outcome of this election," Innes added.

On currency markets the dollar was holding up against the yen after Friday's US jobs data showed another blockbuster number of new positions created and the biggest jump in wages for nine years.

The data solidified expectations the Federal Reserve will press on with its interest rate hikes next month and into 2019.

However, the greenback was lower against the pound after a report in the Sunday Times in Britain said Prime Minister Theresa May had clinched a Brexit deal with the European Union.

Oil prices slipped as the US reimposed sanctions on Iran but with a number of countries including India, Japan and possibly China being given waivers to continue buying from the country.

Adding to the downward pressure are expectations that major producers Saudi Arabia and Russia will ramp up their own exports to make up for the shortfall from Iran.
